THE PRESENT STATE OF KNOWLEDGE OF NOISE IN SHIPS

After an introduction which gives some reasons for the ever-increasing importance of controlling shipboard noise, and mentions the hope that Spanish authorities and shipowners will soon require limits to be imposed on noise levels, the Author presents a broad review of the noise problem in ships. The review is based on the extensive bibliography accompanying the article, and is arranged under the main headings: 1. Preliminary Considerations. Sound and Noise--Main Characteristics of Human Hearing--Measurement Methods and Units. 2. Permissible Noise Levels. Damage to Hearing--Interference with Communications--Discomfort to the Crew--Standards and Recommendations on Noise Levels Acceptable in Ships. 3. Main Sources of Shipboard Noise. Propeller--Machinery--Ventilation and Air-Conditioning Systems. 4. Noise Transmission in Ships. Airborne Transmission--Structureborne Transmission--Connection between the Two Types of Transmission. 5. Main Remedies Possible for Shipboard Noise. Reduction of Noise at its Sources--Reduction of Noise Transmission. Appendix A. Glossary of Acoustics Terms. Appendix B. Comments on Some Acoustics Formulae.
